QUART mamFS

Universal Mammography Test Phantom

The QUART mam FS phantom is designed to be used for QA/QC testing in conventional mammography applications according DIN/IEC requirements.

Only one exposure is required to collect all parameters to determine the imaging quality of the x-ray system. After the exposure, the test image is evaluated visually.

The QUART mam FS phantom complies with IEC 61223-3-2, DIN 6868-7 and DIN 6868-152, as well as the „European Guidelines for Quality Assurance in Mammography Screening” (EPQC), Part 1.

MODE OF OPERATION

QC tests are carried out at initial equipment installation to establish a visual reference. On a regular routine basis, they are meant to ensure the constancy of the system‘s imaging capabilities.

Any deterioration in imaging performance is revealed by the visual evaluation of the test images. The evaluation of grey values, as traditionally required for conventional x-ray technology, is carried out using a densitometer.

A simple assessment of image quality for digital mammography systems is also possible.
